Hi first time posting here, hoping someone can help or redirect me to the relevent topic.
I installed this:

Discount Code for osCommerce Online Merchant v2.3.1 can be downloaded at
http://addons.oscommerce.com/info/7700
Everything admin side works fine, however in testing eg making a dummy order i am getting an error on the checkout page. http://silverbirchcrafts.co.uk/checkout_shipping.php
The error is Warning: Cannot modify header information - headers already sent by (output started at /home/sites/silverbirchcrafts.co.uk/public_html/includes/application_top.php:523) in /home/sites/silverbirchcrafts.co.uk/public_html/includes/functions/general.php on line 33
Ive double checked all the code ive changed as per the readme and everything seems to be in order, hoping someone can help.
Rgds.
